I'm confirmed bisexual, and have been since high school (probably since birth). Assuming bisexuality is a spectrum, with Only Women on one end, and Only Men on the other, and we stay somewhere on the spectrum (some near the middle, others leaning toward one side).
Does your interest slide from one end toward the other, and if so, how often?
I have found my inclinations change about every four years, and, of course, not over night.
Right now I'm lesbian leaning, and have been for a few years. I still like (and have great sex with) guys, but my motor purrs best with a woman.
I have been straight leaning at times, enough to marry men (oops, I knew that pendulum was going to swing) but still need some pussy.
My primary attraction changes, but I'm still bi.
Anyone else, or have you found your comfort zone, and you stay there?
